How do I disable one default widget? e.g. widget "Meta"

thanks!

Comment it out in the source.

If you are concerned about overwriting your changes when you update your source, you can also create a plugin which does something like:

function my_unregister_widgets() {
    wp_unregister_sidebar_widget('meta');
};
add_action( 'widgets_init', 'my_unregister_widgets');

thanks a lot!
